Answer:
The correct answer is option A. Base = 11 cm and height = 13 cm
Step-by-step explanation:
It is given that, height of a triangle is 2 cm more than its base.Then height is increased by 2 cm.Then the area of triangle becomes 82.5 cm²
<u>To find the base an d height of original triangle</u>
Let x be the original base 'b' then the height h = x + 2
New height h = x + 2 + 2 = x + 4
Area = bh/2
82.5= (x(x + 4)/2
165 = x² + 4x
x + 4x - 165 = 0
Solving we get x = 11 and x = -15
Take positive value x = 11
Therefore base = 11 and height = x + 2 = 13 cm
The correct answer is option A. Base = 11 cm and height = 13 cm
Answer:
its D
Step-by-step explanation:
basically all you have to do if cut off the semicircles fins their areas then find the rectangles area and add them all up
The wire is about 11.18 m long. This can be found using the Pythagorean theorem.

Step-by-step explanation:
Answer:
Part A: 7.58974359 gallons (I don't know if you needed to round so I kept the full number).
Part B: 8.871794872 gallons
Step-by-step explanation:
Part A's Steps:
First Step: 350 - 54 = 296
Second Step: 296 ÷ 39 = 7.58974359 (Round if you need to)
Part B's Steps:
First Step: 296 + 50 = 346
Second Step: 346 ÷ 50 = 8.871794872
